10 Best Keyword Research
Tools in 2021

Whether you are new to the world of digital marketing or are a seasoned veteran who has been adapting your online offer to suit the market for the last few years, there are some areas of focus which never move out of the spotlight. SEO and the use of keywords is something that has formed a pinnacle part of an effective online strategy for years – using the power of search engines and organic user searches to match users with the websites and webpages that can help them. 

The keywords you use are essential to your SEO strategy because they define what your content is about – and can be used within the copy itself as well as in the backend development of your website. 


How do Keywords Work?

There are a series of different keyword types that website developers and copywriters can use to bolster their SEO strategy. The best way to look at this and to approach your research is to identify keywords that fall into the following categories:


– Industry-specific keywords, e.g., Summer Clothing

– Customer-defining keywords, e.g., Women’s Clothing

– Product Keywords, e.g., Summer Dress

– Industry-Professional Keywords, e.g., designers in your industry

– Competing Company Keywords, e.g., direct competitors

– Related Keywords, e.g., similar but not directly linked to your offering

– Geotargeted Keywords, e.g., words linking you to your local area


Using a comprehensive selection of these different keyword types, the main goal of your SEO strategy is to get your website onto the search results page of those users who have a problem you can solve, and who are seeking the kind of product or service that you provide. 

With that said, what tools are available to help you identify the most effective keywords? Keep reading for our list of the 10 best keyword research tools for 2021.

One of the most popular on the internet right now, most businesses have heard of SEMrush. This tool works by using data and competitor analysis to support content creators in developing a targeted content plan – telling users how their own selection of keywords compares to that of their direct competitors. As well as keyword research, SEMrush boasts a range of additional features which all support a well-rounded digital plan – though it is one of the pricier tools out there so may not be attainable to start-ups and smaller businesses. 



If it’s affordable keyword support you want, look no further than SEOCockpit. This tool focuses on the low competition keywords (that are therefore cheaper to bid on) and uses rank tracking technology to let you know how well competitor strategies are performing on a daily basis – so that you can take their best and most effective ideas and use them yourself. 



KWFinder is a great tool if you want to benefit from a mixture of short and long tail keywords – giving businesses support in profiting from more detailed keywords as well as the more generic and more competitive ones. KWFinder also provides crucial insight into competitor keyword analysis and uses Google Suggest to literally suggest the best keywords for your SEO strategy based on your product and your target audience. 


Long Tail Pro

As you might have guessed, this tool focuses on long tail keywords which are more specific and thus have a lower rate of competition with other businesses. By inputting a series of different keywords, the tool will present hundreds of suggestions for you, with insight into their profitability and rank value. This tool is particularly beneficial for those who are seeking to add SEO strategy to long form content and blogs. 


SE Ranking

Competitor research is a big part of this tool, which also enables users to undergo a website audit, track keyword ranking, monitor webpage changes, and produce complete marketing plans for new content launch and uploads. This is a more expensive tool compared to some of the others but it allows you to produce complete reports on the status and success rate of your keywords and SEO.



This tool is all about increasing the ranking of your site using SEO, readability and user experience, the frequency of keyword use, and search relevancy. Users are presented with a score that lets them know exactly how well their site is performing as part of an overarching SEO strategy – a great way of monitoring improvement and status. 



Serpstat uses data from competitors, search volume, keyword difficulty and CPC to create an overview of the best keywords to increase your success online and through search engines. It also gives you insight into the success of competitor ads and provides comprehensive information into the quality of your backlinks and link data. 



This is not a cheap tool to use but it does present a well-rounded keyword research tool which uses generic features with precision and combines a keyword research explorer with a comprehensive site audit and a SERPS analysis which lets you know the gaps in existing content and how your strategy can be tailored to meet direct user need. 



Offering a unique set of platforms which allow users to explore untapped niche keyword groups and suggestions, this tool combines fresh ideas with competitor analysis – encouraging users to set targets and establish ranking goals from early on in their strategy. One of the key focuses of Jaaxy is on high traffic niche keywords with little competition, so that you can find those really direct and targeted users. 



The last tool in our list, SEOPowerSuite uses rank tracking to analyse the success of users’ own strategies against their competitors – providing insight into both a local and a global keyword research approach. The auditor feature in particular trawls through websites and provides information relating to more than 40 SEO factors – allowing users to optimise every inch of their website and each webpage individually.
